2-FDCK Crystal, also known as 2-Fluorodeschloroketamine, is a synthetic dissociative substance belonging to the arylcyclohexylamine class. This compound is structurally analogous to ketamine, a well-known dissociative anesthetic, but features a fluorine atom replacing a hydrogen atom in the chemical structure. This modification alters its pharmacological properties, making it a unique compound within the same class. Its molecular formula is C13H16FNO, with a molecular weight of 221.27 g/mol. The compound typically appears in a crystalline form and is noted for its high purity when synthesized through verified chemical methods.

The compound’s dissociative effects arise from its interaction with the NMDA (N-methyl-D-aspartate) receptor antagonism within the brain. By blocking these receptors, 2-FDCK Crystal induces unique effects, such as altered sensory perception, cognitive detachment, and dissociation. These mechanisms of action are being studied for their potential therapeutic applications, including pain management and treatment-resistant depression, although comprehensive clinical studies are limited. It is important to note that 2-FDCK Crystal has not been approved for human medical use, and its pharmacodynamics and pharmacokinetics are still under extensive research.
